Find u and v only please:

Every two triangles are similar. Therefore the sides of triangles are in proportion.

We have the equations:

1.

$\dfrac{3}{5}=\dfrac{3+x}{20}$ <em>cross multiply</em>

$5(3+x)=(3)(20)$ <em>divide both sides by 5</em>

$3+x=(3)(4)$

$3+x=12$ <em>subtract 3 from both sides</em>

$\boxed{x=9}$

--------------------------------------

2.

$\dfrac{3}{4}=\dfrac{9}{y}$ <em>cross multiply</em>

$3y=(4)(9)$

$3y=36$ <em>divide both sides by 3</em>

$\boxed{y=12}$

------------------------------------------

3.

$\dfrac{3}{5}=\dfrac{3+9+u}{60}$

$\dfrac{3}{5}=\dfrac{12+u}{60}$ <em>cross multiply</em>

$5(12+u)=(3)(60)$ <em>divide both sides by 5</em>

$12+u=(3)(12)$

$12+u=36$ <em>subtract 12 from both sides</em>

$\boxed{u=24}$

----------------------------------------------

4.

$\dfrac{3}{4}=\dfrac{24}{v}$ <em>cross multiply</em>

$3v=(4)(24)$

$3v=96$ <em>divide both sides by 3</em>

$\boxed{v=32}$

Below is a scale drawing of the town swimming pool in the drawing the longest side of the pool has length of 10 inches Paco crea

quester [9]

Answer:

2:1 that is 2 inches in real life is equal to 1 inch in the drawing.

Step-by-step explanation:

We are given the following in the question:

Longest side of the pool = 10 inches

Longest side of the pool in drawing = 5 inches

Scale:

We find the ratio of the real length of pool and the measurement of the length of the pool in the drawing.

$\text{Scale} = \dfrac{10\text{ inches}}{5\text{ inches}} = 2:1$

Thus, we can say Paco's new drawing follows a scale of 2:1 that is 2 inches in real life is equal to 1 inch in the drawing.
